But being a regular visitor to the States, I think I would have a better standard of living out there (nicer house with land, etc) as well as easier access to things I enjoy doing (riding, swimming, shooting (clays, not animals!), fishing, outdoors in general).
That's kind of understandable, although travelling much further to ride, and not having a big network of trails to ride would put me off. Nice to visit, where you don't get bored of riding the same trails over and over again but not so nice to live there. Also jobs tend to have way less holiday (for the 75% of people who get paid holiday in the US, it is typically 10 + 8 bank holiday type things, compared to 28 days over here as a statutory minimum), which is a hassle if you aren't self employed.
You can get a lot of the outdoors stuff, bigger houses with land, shootin, fishing etc. just by moving Up North or to Scotland.
